In my experience, package management's routine failure to find/use a 'healthy' repository is a long-standing production problem.
I'm requesting a fix.
Here's a summary:
I run Opensuse 13.1 on numerous machines
Description: openSUSE 13.1 (Bottle) (x86_64)
Current count is ~200.
The machines are installed at multiple locations around the globe.
They're connected to the 'net via a variety of different networks providers.
Some of the machines are directly connected to the 'net, some are behind LAN routers, switches & firewalls.
Package management for all of the machines is handled exclusively via zypper cli.
Each machine has a common core of repositories defined in /etc/zypp/repos.d, and frequently has a number of additional @openSUSE dev (!'home') repos defined.
In ALL cases, the default install of repos sets have been installed with the meta-director as baseurl,
Regular package maintenance consists of
zypper clean --all
The maintenance frequency is nominally 1/wk, often 1/dy, and in devs' cases, often more frequent.
In virtually ALL cases, the update process regularly fails @ retrieving/refreshing the repos' (meta)data.
For example, a typical result is:
Checking whether to refresh metadata for KDE4-Extra-Unstable
Retrieving: repomd.xml .......................................................................................[error]
File '/repodata/repomd.xml' not found on medium 'http://download.opensuse.org/repositories/KDE:/Unstable:/Extra/KDE_Current_…'
Abort, retry, ignore? [a/r/i/? shows all options] (a):
This occurs occassionally for any/all repos, whether the standard distribution repos (security, update, etc), core DM (e.g. KDE*) additional repos, or the more 'esoteric' !home OBS-hosted repos (e.g., security:netfilter).
The failure rate for overall update/upgrade process attempts is, very roughly, ~15%.
The error is NON-recoverable. 'Abort' & 'retry' *never* work.
Chats @ IRC re: the issue typically result in the same '(non)responses' : "wait", "works for me", "prove it", etc.
The ONLY solution(s) that work are:
(1) wait some random amount of time -- typically hours, occassionally days -- until the system magically heals itself,
(2) visit the download.opensuse.org link for the repo, click 'details' for a target page, identify a specific working/available repo for the package(s) of interest, and manually edit baseurl= for the problematic repo.
Neither is tenable for a reliable operating environment. It is simply unmanageable in either a single, local or widely-distributed environment.
(2) is further confounded by the fact that, at any given time, a previously-working, manually-selected repo may, itself, fail, requiring -- yet again -- another manual intervention.
Within the scope of our environment, no other distro's package management system has anywhere near the failure rate demonstrated here. (We've ~600+ other machines running a mix of Centos, Fedora, Debian & Ubuntu).
This has been occurring for literally years, across multiple openSUSE versions, and remains unaddressed. I know, without any doubt, that others experience similar/frequent failures -- it's been a frequent discussion with our partners, as well as in openSUSE* IRC channels.
This needs a fix. As to what, specifically, that fix can/should be -- I'm unclear. If a solution already exists, I'm unaware.
One idea -- a fallback mechanism *within* a repos' definition would be useful
For example, allow in a given repo's def'n, having multiple, numbered baseurls
and add fuction to zypper so that for each repo, the baseurls would be tried in order for any given failure.
By adding, e.g., a
to either/both a given repo's defn, or /etc/zypp(er).conf, the overall process could be terminated if there were "X" # of subsequent fails, indicating a likely systemic problem requiring further intervention.
I'd appreciate hearing from "those responsible for keeping the redirector & repos working" re:
* acknowledgement, or refusal thereof, of the failure issue
* clarification as to why it occurs in the first place
* ideas/suggestions as to what can/should be done to fix it
